1.7 If the Thermal Cut-Out Operates


Chapter 2 Wax DispenserThe Wax Dispenser holds up to 5 litres of wax at a thermostatically controlled temperature. Wax is delivered via a two-position tap: the first position allows wax to be dispensed only while the lever is held down, and the second position allows the lever to be locked open for continuous flow (this may require you to turn the lever). A 0.5mm mesh at the base of the reservoir prevents coarse debris from blocking the delivery assembly. A separate tap heater ensures an even flow of wax.

Figure 1 shows the main features of the Wax Dispenser.

The Wax Dispenser operates over a temperature range of 50°C to 70°C. The outer casing is made from polished stainless steel. The reservoir and lid are made from aluminium, and the tap is chromium-plated brass.

A positive rocker switch controls power to the instrument, and is illuminated when depressed to the I (ON) position. The dial controlling the thermostat setting is graduated to give a guide to the wax temperature, and is fitted with a maximum stop at 70°C. An amber lamp indicates operation of the reservoir heating elements via the thermostat. A red lamp shows you when the thermal safety cut-out has operated.

Note The thermal safety cut-out is a non-resetting secondary thermostat fitted to protect the instrument from overheating.

The power cable has moulded plugs at both terminals. The power inlet socket at the back of the Wax Dispenser has fuses on both the negative line and the positive line for optimum protection. It also incorporates a filter which prevents radio interference.


Do Not:• Use the wax dispenser without wax in the reservoir

• Use abrasives to clean the interior

Do:• Maintain the apparatus in a reasonably clean condition

• Switch off before removing the plug


• Use a drip tray

• Use on a level surface or the tap may not hold onto drips

2.2 Cautionary Notes
